Classification into progressor classes by eGFR slope. a, Examples of linear regression modeling of eGFR vs. time for determination of eGFR slope. One example is given for each of the slow (eGFR slope > − 5 ml/min/year), moderate (slope − 10 to − 5 ml/min/year), and fast (slope ≤ − 10 ml/min/year) progressor classes. b, Stacked bar chart of distribution of histologic scores among different progressor classes. The distribution of histology scores for each category of the 2010 RPS classification system was similar between progressor classes (p values for glomerular, IF/TA, arteriosclerosis, and arteriolar hyalinosis scores of 0.93, 0.88, 0.59, and 0.41, respectively). eGFR, estimated glomerular filtration rate; IF/TA, interstitial fibrosis and tubular atrophy; RPS, Renal Pathology Society.
